import { assertEquals, assertThrows } from "jsr:@std/assert";

assertEquals(tomat(true), [[true]]);

Convert a row vector to a matrix

import { assertEquals, assertThrows } from "jsr:@std/assert";

assertEquals(tomat([5, 6, 3]), [[5, 6, 3]]);

Convert an already formatted matrix

import { assertEquals, assertThrows } from "jsr:@std/assert";

assertEquals(tomat([[1, 2], [3, 4]]), [[1, 2], [3, 4]]);
